A typical 2 slices cooked serving of bacon contains 5.7 grams of protein (35.7 g per 100 g), which makes it a moderate source of protein. That covers roughly 11% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Around 26% of the calories in bacon come from protein, so it is moderately protein-dense. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
Among the 133 meats in the database, bacon ranks 120th by protein per serving, and 451st out of all 796 foods on the site. Set against deli roast beef, another meat entry in the database, a serving carries about 0.5 g more protein (deli roast beef has 5.2 g per 1 oz).
It is a complete protein - it supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own. The serving above is counted by piece at 16 g. Because pieces vary, the per-100 g figure is the one to use when comparing this against a food measured a different way.
